💡 How to Save Money on VAT: 10 Legal Strategies

If close to £90,000 turnover, consider timing invoices or deferring sales to stay below threshold.

Pay VAT only when paid by customers - can defer VAT payments by months.

Potential Saving: 20% of business expenses
Reclaim VAT on all eligible business expenses - equipment, travel, professional fees.
5. Time Large Purchases
Potential Saving: £2,000+ on £10,000 equipment
Register for VAT before making large equipment purchases to reclaim 20% VAT.

💡 Advanced VAT Money-Saving Strategies
1. Optimize Your VAT Group
Saving: Eliminate inter-company VAT
If you have multiple companies, register as a VAT group to avoid VAT on transactions between group companies.
2. Use Partial Exemption Rules
Saving: Reclaim VAT on mixed supplies
If you make both taxable and exempt supplies, you may still reclaim some input VAT using partial exemption calculations.
3. Consider VAT Avoidance Schemes
Warning: High risk, potential penalties
Legitimate schemes exist but carry risks. Always get professional advice before implementing any VAT planning scheme.
4. Plan Major Purchases
Saving: £2,000+ on £10,000 equipment
Register for VAT before making large purchases to reclaim 20% VAT. Time purchases with registration if possible.
5. Use Bad Debt Relief
Saving: Reclaim VAT on unpaid invoices
If a customer doesn't pay after 6 months, you can reclaim the VAT you've already paid to HMRC.
6. Consider Deregistration
Saving: Simplify admin for declining businesses
If turnover falls below £88,000, you can deregister to simplify your affairs (but lose input VAT reclaim).
❌ Common VAT Mistakes That Cost Money
Not Registering on Time
Cost: Penalties + interest
Must register within 30 days of exceeding threshold. Late registration can result in penalties and backdated VAT charges.
Wrong VAT Scheme Choice
Cost: £1,000s in unnecessary VAT
Many businesses automatically choose standard VAT when flat rate would save thousands. Always compare schemes.
Not Claiming Input VAT
Cost: 20% of expenses
Failing to reclaim VAT on legitimate business expenses essentially gives HMRC free money.
Incorrect VAT Treatment
Cost: Penalties + corrections
Applying wrong VAT rates or treating exempt supplies as taxable can trigger HMRC investigations.
